The MUYHSMFF 4-Pin 3.5mm to dual 3-pin 3.5mm Headset Adaptor features one 3.5mm Male and two 3.5mm Female connectors, allowing you to add a microphone input as well as an audio output to your PC or Laptop, through a single 3.5mm audio port. While some of the newer laptops from Apple and Dell feature only a single (4-pin) 3.5mm audio port that supports both audio input and output, this innovative headset Adaptor breaks the audio port out into two distinct ports – one that can be used for a microphone connection, and the other for connecting external speakers. Featuring a compact, yet sturdy design, the headset Adaptor delivers the perfect solution for applications that require portability, and takes up very little space in your laptop bag.
